Because shadow boards hang in a
central location,
people need to walk more.
Picking up and bringing tools

The more frequently tools are used,
The more walking,
The less likely the tools
are to be returned

ARE
SHADOW BOARDS
STRONG STANDARDS ?
Decide for yourself

People tend to take tools from the
shadow board,
But do not bring it back
(and keep it to themselves)

And besides:
When the shadow board has an empty
spot,
WHERE is the missing tool?

Where is the
screwdriver?
Who has it?
WHERE?

Shadow boards are easy to make
But
Hard to sustain
5th S SUSTAIN

• There are main tasks and side tasks
• People tend to forget side tasks that come
after main tasks
• Such as forgetting to put the fuel cap back on
the gas tank (side task) after filling up (main
task)
POST COMPLETION ERROR

• Shadow boards are fine
• But what works sometimes
better?
ARE THERE ALTERNATIVES?

Store tools where they are used.
Not in a central location

• Indeed, sometimes you need
several copies of the same tool
in different places
• Which is more inventory
SIDE EFFECT
INVENTORY

Make the shadow board
Movable
So you can grab it when needed
SEARCHING

• A shadowboard on wheels
• Give it a fixed place
ALTERNATIVES

Rather no tools,
Replace them with smart fastening
systems
(no tools needed)

No tools,
No shadow board
No compliance
